Indigo may be CS value for money, but not a good option.

I disagree with comments that indigo CS is a good car. It’s
my personal experience. It is very bad customer service tata motors have. Worst
customer service I have ever experienced in my life. They are good in pre-sales
activities. Once you become a customer you have to suffer a lot. Be ready to fight
with tata motors executives.

About the car, it may be giving a sedan for a good price but
the performance is very poor. I have replaced starter twice (at my own expense)
and recently replaced the entire key system within one year period.

It is only your luck if you are getting a good performance
or satisfied with a tata motors vehicle.
